Four data loggers record the temperature at the start and at the end of an environmental test.
| Data logger | Temperature at start | Temperature at end |
|---|---|---|
| W | −18 ∘C-18\,^\circ\mathrm{C}−18∘C | 267 K |
| X | 7 ∘C7\,^\circ\mathrm{C}7∘C | 295 K |
| Y | 250 K | −8 ∘C-8\,^\circ\mathrm{C}−8∘C |
| Z | 4 ∘C4\,^\circ\mathrm{C}4∘C | 291 K |
